WINDING-INDICATOR FOR CLOCKS.

Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed March 17, 1906. Serial 1107306665- To all whont it mayconcern:

Be it known that I, THEODORE J. ARNE- SON, a citizen of the UnitedStates, residing at Westbrook, in the county of Cottonwood, State ofMinnesota, have invented certain new and useful Improvements in Winding-Indicators for Clocks; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to clocks, and more particularly to indicatorstherefor, and has for its object to provide a mechanism arranged toindicate the necessity for Winding a clock when the latter has run down,another object being to provide an indicator which will be simple instructure and arrangement and Which will include a novel arrangement ofparts.

Other objects and advantages) Will be apparent from the followingdescription.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 isa view of a clock provided with the present invention. Fig. 21s an elevational view of the releasing mechanism. Fig. 3 is a top planview of the releasing mechanism. Fig. 4 is a longitudinal section of thereleasing mechanism, taken on line 4 4 of Fig. 3.

Referring now to the drawings, there is shown a clock including a casing5, having a back 6, to which there is secured the usual spring-actuatedmechanism 7, which includes a coil driving-spring 8. Secured to the back6, below the works 7, there is a bracket 9, in which there is jour'naleda horizontal forwardly-extending shaft 10, having mounted thereon anotched disk 11. An arm 12 is secured to the shaft and extends u wardlyat one side of the spring 8, and the s aft is held with this arm againstthe spring by a helical spring 13, which is engaged with the shaft 10and which is secured to the bracket 9, it being understood that the armrests against the convex surface of the outermost layer of the spring,so that the arm will be moved to move the shaft a ainst the action ofthe spring 13 as the c ockwork runs down and the spring 8 movesoutwardly from the shaft.

A stop-finger 14 extends downwardly from the shaft 10 and engages theside of the casbracket there is an arm 16, which extends over the disk11 and which has a laterallyturned finger 17 at its free end, which isarranged to rest upon the eriphery of the disk. A spring-actuated a armmechanism 18 is secured to the back 6 below the bracket 15 and has theusual stop mechanism 19, with which there is connected a rod 20, and thearrangement is such that when this rod is moved downwardly the alarmmechanism is released. The rod 20 is connected with the arm 16,, and thearrangement is such that when this arm is in raised position, with itsfinger 17 resting upon the periphery of the disk 11, the alarm mechanismis held against operation. The finger 17 is so located upon the disk 11that when the shaft 10 is rotated by expansion of the spring 8, asmentioned above, the notch 11 of the disk 11 is brought into positionfor downward movement of the finger 17 thereinto, which releases thealarm mechanism.

The alarm mechanism 18 includes an oscillating shaft 22, to which theclapper 23 is connected, and an arm 24 is connected with the shaft andextends horizontally, this arm having the rod 20 secured thereto. Itwill thus be seen that when the shaft 22 is oscillated the arm 24. willbe moved vertically in opposite direction, and when it is moved upwardlythe finger 17 of the arm 15 is moved out of the notch 11, so that thespring 13 is free to bring the unnotched portion of the disk 11 beneaththe finger 17 to hold the alarm mechanism against operation. It willthus be seen that after the clock has run down and the. spring 8 hasexpanded sufficiently to release the alarm mechanism 18 the latter willbe sounded, when the spring 8 may berewound to permit of movement of thedisk 11 to its normal position under the action of the s ring 13, thealternate upward movement 0 the arm 16 by the alarm mechanism 18permitting of this movement of the disk, as just described. If it sohappens that the alarm mechanism runs down before the spring 8 isrewound, the alarm mechanism may then be wound after rewinding of thespring 8, when the first upward movement of the arm 24 will raise thearm 16, permitting the disk 11 to move into normal position and hold thealarm mechanism against operation until the spring 8 shall have beenexpanded.

hat is claimed is- The combination with a clock having anactuating-spring arranged for expansion as the clock runs down, of analarm mechanism, and means for holding said mechanism against operation,said holding means consisting of a revoluble shaft, an arm carried bythe shaft and lying in position for engagement and movement by thespring when the latter expands, to move the shaft, a notched diskmounted upon the shaft, a pivoted arm having a finger resting upon theperiphery of the disk, said shaft being arranged for movement by thespring to bring the notch of the disk into position for passa e of thefinger therethrough, means for holding the shaft yieldably againstmovement by the spring, and connections between the second arm and thealarm mechanism, said connections being arranged to hold the alarmmechanism against movement when the fin er is enga 'ed with theperiphery of the disi.

n testimony whereof I aflix my signature in presence of two witnesses.
